The LXD container hypervisor

10x the density of ESX, 25% faster, with zero latency

It has been time i've been waiting for LXC to be stable to use in production.

Let me tell you why i think that: LXD works like a daemon for LXC, it allows you to establish a communication handshake between your LXC client and any machine you have with LXD hosting several containers.

Lightweight and simple, just pop your command-line client and start creating, starting, stopping, cloning and snapshotting. Moving containers between LXD hosts it's also as easy and performant. Here are the main LXD advantages:

Secure by design (unprivileged containers, resource restrictions and much more)

This will install the LXD daemon, client tools and also LXC. LXD is not a replacement for LXC, it's just a daemon and a new set of client libraries and tools that allow you to manage remote servers that host the containers.

Now you can create a new container:

$> lxc create odoo1

Or in a remote host:

$> lxc create host1:odoo1

List existing containers:

$> lxc list host1:

Get access to the container's console:

$> lxc exec host1:odoo1 bash

Lots of other commands just use --help$> lxc --help

config - Manage configuration

copy - Copy containers within or in between lxd instances.

delete - Delete containers or container snapshots.

exec - Execute the specified command in a container.

file - Manage files on a container.

help - Presents details on how to use LXD.

image - Manipulate container images.

info - List information on LXD servers and containers.

launch - Launch a container from a particular image.

list - Lists the available resources.

move - Move containers within or in between lxd instances.

profile - Manage configuration profiles.

publish - Publish containers as images.

remote - Manage remote LXD servers.

restart - Changes state of one or more containers to restart.

restore - Set the current state of a resource back to a snapshot.

snapshot - Create a read-only snapshot of a container.

start - Changes state of one or more containers to start.

stop - Changes state of one or more containers to stop.

version - Prints the version number of this client tool.

In the remote host, you need to do the following for getting access:

lxc config set core.https_address "[::]"

lxc config set core.trust_password some-password

We sure love the concept and will be testing this "stable version" on test servers first ;)
